A cactus is a type of succulent plant that stores water in its thick stems and leaves and has spines or spikes to protect itself from predators. Cacti are native to many parts of the world, including Arizona, which is home to more than 50 species of cacti, such as barrel cactus, cholla, pincushion cactus, and saguaro. People love planting these prickly plants as outdoor ornamentals because they provide unique texture and form to landscape designs while also being low-maintenance since they don’t require much water or fertilizer. In addition, some species feature beautiful flowers in shades of yellow, pink, and red that add a splash of color to any garden.

These 8 Cacti can be found in the state of Arizona.

Growing Cacti in Arizona

Arizona is located in USDA Hardiness Zones 4b through 10b, depending on the region and elevation. Generally speaking, Zone 5 is found at higher elevations in Arizona’s mountain ranges like Flagstaff and the White Mountains, while Zones 6-10 are present throughout most of the state. This makes cacti an ideal plant choice for many areas in Arizona, as they tend to thrive best within these hardiness zones. Cacti can add a unique aesthetic to any garden or outdoor space due to their spiny characteristics and a wide variety of shapes and sizes. Additionally, they require minimal care, which makes them an attractive option for those who do not have the time or resources to devote large amounts of effort to gardening.

The saguaro cactus (Carnegia gigantia) is an iconic symbol of the deserts of the American Southwest, particularly Arizona. It can grow up to 40 feet and live for over 200 years! Its thick ribbed stems protect it from heat during the summer and cold temperatures in winter. The bright white flowers bloom at night in springtime, attracting pollinators such as bats, hummingbirds, and moths. The saguaro also produces a sweet edible red fruit that has been harvested by Native Americans for centuries as a source of food. Not only is this species important ecologically, but it is also culturally significant — it appears regularly in traditional art and literature of Indigenous peoples like the Tohono O’odham Nation, who have inhabited its habitat since time immemorial.

This type of cactus requires minimal maintenance and can survive even in extreme climates due to its drought-tolerant nature. It is winter hardy to -10 degrees Fahrenheit! When compared with other types of chollas, cane cholla is considered more aggressive due to its large number of spines and ability to spread quickly across an area if given enough space or nutrients. Despite this fact, however, it remains a popular choice for landscaping due to its attractive appearance and hardiness against pests and diseases.
